"Motion" or "Momentum"
A stationary object will not move unless a force is applied to it.
No. In order for an object to remain stationary, the forces on it must be balanced. If the pull on the object increases, the force of static friction must also increase.

If an object is stationary on a surface then the forces acting on it are the Gravitational force and the Normal force(the force of the surface pushing back against the object). Technically you could be pulling(or pushing) that object from opposite directions with equal forces and it would remain stationary. The important thing to understand is that a stationary object remains stationary so long as the net forces applied to it equal zero.
Static friction. The frictional force is greater then the force applied, meaning the object can't move.
It remains stationary
No. In order for an object to remain stationary, the forces on it must be balanced. If the pull on the object increases, the force of static friction must also increase.
Inertia-every body remains stationary until a force is applied to it.
